What medicinal compounds this plant contains?
This plant contains the medicinal compounds apiin, apiol, apigenin, myristicin, and bergapten. Apiin is a glycoside that provides unique bioactive properties to the parsley leaves. The essential oil component apiol is often studied for its specific physiological effects. Apigenin acts as a potent flavonoid with significant antioxidant and anti-inflammatory potential. Myristicin and bergapten further contribute to the complex chemical profile utilized in various therapeutic applications.
According to a study published by "Fitoterapia", the HPLC-DAD-ESI-MS/MS profile identifies apiin and coumaric acid derivatives as the main compounds in the PCC-AP extract. This aqueous extract of aerial parts exhibited the highest in vitro antiplatelet activity with an IC50 of 2.92 mg/mL when using ADP and collagen as agonists. Oral administration of the PCC-AP extract in rats caused 50% inhibitory activity in deep vein thrombi at 65 mg/kg and 50% inhibitory activity in arterial thrombi formation at 200 mg/kg. These results were observed without a cumulative effect after a consecutive five-day administration. The extracts from different parts of this curly-leaf variety of Petroselinum crispum demonstrate significant antiplatelet, anticoagulant, and antithrombotic activity.

What are the herbal preparations of this plant?
This plant is Petroselinum crispum, which is utilized to create various medicinal herbal preparations including aqueous extracts, essential oils, powders, ethanolic extracts, and parsley juice. Aqueous extracts are commonly prepared by steeping the plant in water to harness its water-soluble nutrients. Essential oils are derived through steam distillation to concentrate the aromatic and therapeutic volatile compounds. The dried leaves can be processed into a fine powder for easy integration into supplements or food. Ethanolic extracts use alcohol as a solvent to pull out stronger bioactive phytochemicals that water cannot dissolve. Finally, fresh parsley juice provides a direct source of concentrated vitamins and minerals in a liquid form.
According to a study published by "Journal of ethnopharmacology", aqueous and methanolic extracts of Petroselinum crispum were tested for acetylcholinesterase inhibitory activity using the Ellman colorimetric method. This plant was among 11 plants used in Danish folk medicine for improvement of memory and cognition that were screened. Petroselinum crispum exhibited moderate inhibition of the enzyme. This moderate inhibition was defined as more than 15% at 0.1 mg/ml.
The main herbal preparations of this plant are shown in the list below.
- Aqueous extract
- Essential Oil
- Powder

What side effects this plant can have?
This plant can cause adverse health effects including antiplatelet activity, cytotoxicity, prolonged bleeding time, skin irritation, and toxicity from trace elements. Its ability to inhibit platelet aggregation can lead to a prolonged bleeding time, which poses risks for individuals undergoing surgery. Some studies have also indicated potential cytotoxicity, suggesting that certain compounds may be harmful to cellular structures. Topical contact with the plant may result in skin irritation or allergic reactions in sensitive individuals. Furthermore, the accumulation of toxicity from trace elements present in the plant can pose additional long-term health concerns.
According to a study published by "Journal of complementary & integrative medicine", geniins isolated from Petroselinum crispum leaves demonstrate potent antiplatelet activity by inhibiting human blood platelet aggregation and adhesion to collagen. These geniins, which include kaempferol and apiogenin, inhibit aggregation induced by thrombine, ADP, and collagen in a dose-dependent manner. The strongest effect was observed in collagen induced aggregation with an IC50 of 0.08 ± 0.01 mg/ml. Additionally, the adhesion of human platelets to collagen was decreased by over 75 % when using geniins at a concentration of 0.3 mg/ml. These findings suggest that Petroselinum crispum may be an important source of beneficial compounds to decrease thrombosis and cardiovascular diseases.
The main side effects this plant can have are shown in the list below.
